• #1 Huntington’s disease: Symptoms, causes, and treatment

  https://www.medicalnewstoday.com/articles/159552

  Huntingtons disease is a rare and incurable hereditary disorder that damages brain cells. Early signs include coordination problems and memory lapses. In the later stages, people may need full-time care. […] HD causes a variety of physical, behavioral, and cognitive symptoms that typically appear in people aged 30-50. […] However, 5-10% of people with HD develop symptoms before age 20. This is called juvenile Huntingtons disease and may progress more quickly. […] The types, frequency, and severity of HD symptoms may also vary between individuals. For example, some may experience depression first and then changes in their motor skills, while others may show physical signs. […] HD may cause symptoms that affect a person’s stature and gait, as well as voluntary and involuntary movements.

  Huntington’s disease symptoms can develop at any time, but they often begin when people are in their 30s or 40s. […] Huntington’s disease usually causes movement disorders. It also causes mental health conditions and trouble with thinking and planning. These conditions can cause a wide spectrum of symptoms. The first symptoms vary greatly from person to person. Some symptoms appear to be worse or have a greater effect on functional ability. These symptoms may change in severity throughout the course of the disease. […] The movement disorders related to Huntington’s disease may cause movements that can’t be controlled, called chorea. Chorea are involuntary movements affecting all the muscles of the body, specifically the arms and legs, the face and the tongue. They also can affect the ability to make voluntary movements. Symptoms may include: Involuntary jerking or writhing movements. Muscle rigidity or muscle contracture. Slow or unusual eye movements. Trouble walking or keeping posture and balance.

  Middle Stage: Symptoms: More pronounced functional decline and motor issues, such as involuntary movements (chorea), balance problems, eyes-related symptoms and difficulty walking. Common signs: Cognitive decline and mood disturbances, including anxiety or aggression. Impact: Daily activities require assistance and communication becomes more challenging. […] Late Stage: Symptoms: Severe motor impairments, inability to walk, speak or swallow effectively. Common signs: Cognitive abilities are significantly affected, often leading to dependency on full-time care. Chorea is often replaced by stiffness (rigidity), abnormal muscle contractions (dystonia) and slow movement (bradykinesia). Impact: Quality of life depends on palliative care to manage symptoms and ensure comfort. […] Early Onset Huntingtons Disease (Juvenile Huntingtons Disease): Symptoms: Stiff movements, speech difficulties, behavioral changes and a decline in academic performance. Seizures are more common in early onset than in adult-onset cases. Progression: The disease tends to progress faster in juvenile cases compared to adult-onset Huntingtons.

  Signs and symptoms of Huntington’s disease most commonly become noticeable between the ages of 30 and 50 years, but they can begin at any age and present as a triad of motor, cognitive, and psychiatric symptoms. When developed in an early stage, it is known as juvenile Huntington’s disease. In 50% of cases, the psychiatric symptoms appear first. These can precede the motor symptoms by many years. Disease progression is often described in early stages, middle stages and late stages with an earlier prodromal phase. In the early stages, subtle personality changes, problems in cognition and physical skills, irritability and mood swings occur, all of which may go unnoticed. Almost everyone with HD eventually exhibits similar physical symptoms, but the onset, progression, and extent of cognitive and behavioral symptoms vary significantly between individuals.

  In early stage HD, individuals are largely functional and may continue to work, drive, handle money, and live independently. Symptoms may include minor involuntary movements, subtle loss of coordination, difficulty thinking through complex problems, and perhaps some depression, irritability, or disinhibition. […] In middle stage HD, individuals lose the ability to work or drive and may no longer be able to manage their own finances or perform their own household chores, but will be able to eat, dress, and attend to personal hygiene with assistance. Chorea may be prominent, and people with HD have increasing difficulty with voluntary motor tasks. There may be problems with swallowing, balance, falls, and weight loss. Problem solving becomes more difficult because individuals cannot sequence, organize, or prioritize information.

• #17 Huntington’s disease – Wikipedia

  https://en.wikipedia.org/wiki/Huntington%27s_disease

  The most characteristic initial physical symptoms are jerky, random and uncontrollable movements called chorea. Many people are not aware of their involuntary movements, or impeded by them. Chorea may be initially exhibited as general restlessness, small unintentionally initiated or uncompleted motions, lack of coordination, or slowed saccadic eye movements. These minor motor abnormalities usually precede more obvious signs of motor dysfunction by at least three years. The clear appearance of symptoms such as rigidity, writhing motions, or abnormal posturing appear as the disorder progresses. These are signs that the system in the brain that is responsible for movement has been affected. Psychomotor functions become increasingly impaired, such that any action that requires muscle control is affected. When muscle control is affected such as rigidity or muscle contracture this is known as dystonia. Dystonia is a neurological hyperkinetic movement disorder that results in twisting or repetitive movements, that may resemble a tremor. Common consequences are physical instability, abnormal facial expression, and difficulties chewing, swallowing and speaking.

  Cognitive abilities are progressively impaired and tend to generally decline into dementia. Especially affected are executive functions, which include planning, cognitive flexibility, abstract thinking, rule acquisition, initiation of appropriate actions, and inhibition of inappropriate actions. Different cognitive impairments include difficulty focusing on tasks, lack of flexibility, a lack of impulse, a lack of awareness of one’s own behaviors and abilities and difficulty learning or processing new information. As the disease progresses, memory deficits tend to appear. Reported impairments range from short-term memory deficits to long-term memory difficulties, including deficits in episodic (memory of one’s life), procedural (memory of the body of how to perform an activity), and working memory.

  Some people with HD do not develop chorea; instead, they may become rigid (stiff) and move very little or not at all. This condition is called akinesia. Other people may start out with chorea but become rigid as the disease progresses. […] Physical changes may include slurred speech and problems with swallowing, eating, speaking, and especially walking. People with HD may lose weight because of problems with feeding, swallowing, choking, and chest infections. Other symptoms may include insomnia (having trouble sleeping), loss of energy, fatigue, and seizures. Eventually the person will need to stay in bed or in a wheelchair. […] Changes in thinking (cognitive changes) may include problems with attention or judgment and having difficulty solving problems or making decisions. Other changes may include trouble with driving, prioritizing (deciding which things are more important to do and which are less important), and organizing, learning new things, remembering a fact, putting thoughts into words, or answering a question. These cognitive changes get worse as the disease progresses, until people with HD are not able to work, drive, or care for themselves.

  People with HD show a wide range of symptoms at the onset of the disease. While most people with HD develop the motor symptoms in their forties and fifties, subtle changes may arise much earlier. […] About 10% have onset of motor symptoms after age 60 and 10% have Juvenile onset HD, where symptoms manifest before age 20. […] The movement disorder of HD includes emergence of involuntary movements (chorea) and the impairment of voluntary movements, which result in reduced manual dexterity, slurred speech, swallowing difficulties, problems with balance, and falls. Chorea typically progresses through the middle stages of HD, but often declines as rigidity increases in the later stages. […] The cognitive disorder of HD is characterized by a reduction of speed and flexibility in mental processing. Cognitive losses accumulate and people with HD develop more global impairments in the later stages of the disease.

  The behavioral or psychiatric disorder in HD is less predictable. People with HD may suffer from depression and other conditions found in the general population, such as mania, obsessive compulsive disorder, or various forms of psychosis. However, almost all people with HD will manifest disease-specific personality and behavioral changes as part of what might be termed a hypofrontal or dysexecutive syndrome, characterized by apathy, irritability, impulsivity, and obsessionality, with potentially severe consequences for the HD person’s marital, social, and economic well-being.

  Chorea is the most common involuntary symptom of adult HD. These are uncontrollable movements like spasms, jerks, and twitches that may affect any body part. […] Over time, uncontrollable movements occur more often and usually with more intensity. Eventually, they may become slower as the muscles become more rigid. […] Approximately 40% of people with HD will develop depression at some point. […] Cognitive symptoms typically worsen over time and may lead to dementia. Eventually, someone may require full-time care. […] Most adults with HD live for 10-25 years after a diagnosis, while juvenile HD may be fatal within 10 years of a diagnosis. […] HD is a hereditary condition that causes damage to a person’s brain cells. This may cause symptoms that are physical, behavioral, cognitive, and emotional.

  Huntingtons disease (HD) results from the degeneration of neurons of structures deep within the brain, the basal ganglia, which are responsible for movement and coordination. It is a progressive, neurodegenerative disorder typically characterized by involuntary movements (chorea), behavioral and personality changes and cognitive decline (dementia). […] The characteristic triad includes physical symptoms (e.g., involuntary movements, restlessness, fidgety, loss of balance, awkward gait, poor coordination, dysarthria), cognitive changes (e.g., memory loss, inability to multitask, poor calculations, disorganization), and emotional and behavioral disturbances (e.g., depression, apathy, paranoia, anger, withdrawal, anxiety). Early symptoms may include personality changes, such as mood swings, irritability, apathy, depression, anger or aggression. Early in the disease, cognitive decline may manifest as memory and learning difficulties, judgment impairment, and trouble with driving, answering questions or making decisions. As the disease progresses, concentration and focus on intellectual tasks become increasingly difficult. Weight loss, not due to decreased caloric intake, is a common feature of patients with HD.

Chorea may be severe, but more often it is replaced by rigidity, dystonia, and bradykinesia. Psychiatric symptoms may occur at any point in the course of the disease, but are harder to recognize and treat late in the disease because of communication difficulties.

Later, it also makes your arms, legs and torso move uncontrollably. […] Huntingtons disease is a progressive condition. This means that your symptoms get worse over time. Complications could include worsening symptoms, like: Dementia (loss of brain function, memory loss, personality changes). Physical injury from involuntary movements or falls. Difficulty swallowing, eating or drinking (malnutrition). Inability to walk without assistance. […] Huntingtons disease is a progressive condition. This means it slowly gets worse over time. The way the condition progresses varies for each person, but may include: Early stage: Symptoms are mild. You might feel moody or clumsy and struggle with complex thinking. You may also have small, uncontrollable movements, but typically, you can continue your everyday activities. Middle stage: Physical and mental changes make working, driving and household chores very difficult. You may have trouble swallowing, which can make speaking and eating meals challenging but not impossible. Your balance may be off, increasing your risk of falling.

  In late stage HD, individuals require assistance in all activities of daily living. Although they are often nonverbal and bedridden in the end stages, it is important to note that people with HD seem to retain some comprehension. Chorea may be severe, but more often it is replaced by rigidity, dystonia, and bradykinesia. Psychiatric symptoms may occur at any point in the course of the disease, but are harder to recognize and treat late in the disease because of communication difficulties.

  In early stage HD, individuals are largely functional and may continue to work, drive, handle money, and live independently. Symptoms may include minor involuntary movements, subtle loss of coordination, difficulty thinking through complex problems, and perhaps some depression, irritability, or disinhibition. […] In middle stage HD, individuals lose the ability to work or drive and may no longer be able to manage their own finances or perform their own household chores, but will be able to eat, dress, and attend to personal hygiene with assistance. Chorea may be prominent, and people with HD have increasing difficulty with voluntary motor tasks. There may be problems with swallowing, balance, falls, and weight loss.

  Huntington’s disease (HD) is an inherited disorder that causes nerve cells (neurons) in parts of the brain to gradually break down and die. The disease attacks areas of the brain that help to control voluntary (intentional) movement, as well as other areas. People living with HD develop uncontrollable dance-like movements (chorea) and abnormal body postures, as well as problems with behavior, emotion, thinking, and personality. […] Symptoms of HD typically appear in middle-aged people (adult HD). They can also appear in children (juvenile HD), but this is rare. The disease gets worse over time.

• #85 Huntington’s disease – Wikipedia

  https://en.wikipedia.org/wiki/Huntington%27s_disease

  The most characteristic initial physical symptoms are jerky, random and uncontrollable movements called chorea. Many people are not aware of their involuntary movements, or impeded by them. Chorea may be initially exhibited as general restlessness, small unintentionally initiated or uncompleted motions, lack of coordination, or slowed saccadic eye movements. These minor motor abnormalities usually precede more obvious signs of motor dysfunction by at least three years. The clear appearance of symptoms such as rigidity, writhing motions, or abnormal posturing appear as the disorder progresses. These are signs that the system in the brain that is responsible for movement has been affected. Psychomotor functions become increasingly impaired, such that any action that requires muscle control is affected. When muscle control is affected such as rigidity or muscle contracture this is known as dystonia. Dystonia is a neurological hyperkinetic movement disorder that results in twisting or repetitive movements, that may resemble a tremor. Common consequences are physical instability, abnormal facial expression, and difficulties chewing, swallowing and speaking.

  Myoclonus is commonly observed in patients with juvenile-onset HD and is rarely reported as a predominant and disabling motor feature in patients with adult-onset HD. […] As the disease progresses, chorea often spontaneously subsides in HD patients. However, parkinsonism can develop and progress to akinesia, severe rigidity, and mutism in the final stages. […] In HD, the progressive deterioration of voluntary motor control is prevalent in gait, balance, coordination, oculomotor function, swallowing, and speech. This deterioration is correlated with an acceleration of functional decline. […] After clinical manifestation, HD patients exhibit steady neurological deterioration. Many studies have attempted to measure the progression of HD. The annual progression rates derived from the results of these studies are summarized in Table 2. Notably, although most neurological symptoms steadily deteriorate after onset, chorea progresses quickly in the early stages and reaches a plateau before worsening as the disease progresses.

  Huntington disease (HD) is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Mean age at onset of symptoms is 30-50 years. In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at school (Juvenile Huntington’s disease; JHD). The classic sign is chorea that gradually spreads to all muscles. All psychomotor processes become severely retarded. Patients experience psychiatric symptoms and cognitive decline. The progression of the disease leads to a complete dependency in daily life, which results in patients requiring full-time care, and finally death. The most common cause of death is pneumonia, followed by suicide. […] The nuclear symptoms and signs of Huntington’s disease (HD) consist of motor, cognitive and psychiatric disturbances. Other less well-known, but prevalent and often debilitating features of HD include unintended weight loss, sleep- and circadian rhythm disturbances and autonomic nervous system dysfunction. The mean age at onset is between 30 and 50 years, with a range of 2 to 85 years. The mean duration of the disease is 17-20 years. The progression of the disease leads to more dependency in daily life and finally death. The most common cause of death is pneumonia, followed by suicide.

• #101 Huntington’s disease – Wikipedia

  https://en.wikipedia.org/wiki/Huntington%27s_disease

  Huntington’s disease (HD), also known as Huntington’s chorea, is an incurable neurodegenerative disease that is mostly inherited. It typically presents as a triad of progressive psychiatric, cognitive, and motor symptoms. The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities, which precede the motor symptoms for many people. The definitive physical symptoms, including a general lack of coordination and an unsteady gait, eventually follow. Over time, the basal ganglia region of the brain gradually becomes damaged. The disease is primarily characterized by a distinctive hyperkinetic movement disorder known as chorea. Chorea classically presents as uncoordinated, involuntary, „dance-like” body movements that become more apparent as the disease advances. Physical abilities gradually worsen until coordinated movement becomes difficult and the person is unable to talk. Mental abilities generally decline into dementia, depression, apathy, and impulsivity at times. The specific symptoms vary somewhat between people. Symptoms usually begin between 30 and 50 years of age, and can start at any age but are usually seen around the age of 40. The disease may develop earlier in each successive generation. About eight percent of cases start before the age of 20 years, and are known as juvenile HD, which typically present with the slow movement symptoms of Parkinson’s disease rather than those of chorea.

It causes: Progressive loss of thinking skills (dementia) […] Symptoms progress over five to twenty years until death. Treatment is focused on managing symptoms. There is no treatment that slows, stops, or reverses the progression of the disease. […] The damage and loss of nerve cells progresses over the years. It leads to a progressive decline in thinking and movement, among many other symptoms. […] In children with childhood-onset HD, common symptoms at the onset include: Stiffness (rigidity) of the trunk or limbs. This can sometimes lead to a stiff gait or falling. […] In an older child with adolescent-onset HD, common initial symptoms include: Involuntary dance-like movements (chorea)

Impact: Quality of life depends on palliative care to manage symptoms and ensure comfort. […] Early Onset Huntingtons Disease (Juvenile Huntingtons Disease): Symptoms: Stiff movements, speech difficulties, behavioral changes and a decline in academic performance. Seizures are more common in early onset than in adult-onset cases. Progression: The disease tends to progress faster in juvenile cases compared to adult-onset Huntingtons.

  After Huntington’s disease starts, a person’s ability to function gradually gets worse over time. How quickly the disease gets worse and how long it takes varies. The time from the first symptoms to death is often about 10 to 30 years. Juvenile Huntington’s disease usually results in death within 10 to 15 years after symptoms develop. […] Eventually, a person with Huntington’s disease requires help with all activities of daily living and care. Late in the disease, the person will likely be confined to a bed and unable to speak. Someone with Huntington’s disease is generally able to understand language and has an awareness of family and friends, though some won’t recognize family members.

  A less common form of Huntington’s disease known as the juvenile form begins in childhood or adolescence. It also involves movement problems and mental and emotional changes. Additional signs of the juvenile form include slow movements, clumsiness, frequent falling, rigidity, slurred speech, and drooling. School performance declines as thinking and reasoning abilities become impaired. Seizures occur in 30 percent to 50 percent of children with this condition. Juvenile Huntington’s disease tends to progress more quickly than the adult-onset form; affected individuals usually live 10 to 15 years after signs and symptoms appear.

• #112 Huntington’s Disease Stages And Progression – Klarity Health Library

  https://my.klarity.health/huntingtons-disease-stages-and-progression/

  Huntingtons disease is characterised by the degeneration of the neurons in the brain (mainly the basal ganglia and cerebral cortex). This degeneration can lead to involuntary choreatic movements alongside cognitive and behavioural problems. HD usually affects people who are 30-50 years old, but can appear earlier if there are more CAG repeats the longer the CAG repeats, the earlier the symptoms will be. Some of the symptoms of Huntingtons include: Concentration difficulties, Memory lapses, Clumsiness, Involuntary jerking or fidgeting of the limbs/body, Difficulty moving, Difficulty swallowing, speaking, and breathing, Depression, mood swings, and personality changes. […] As mentioned previously, the symptoms start as subtle movement difficulties, mood, and personality changes that progressively get worse with cognitive impairment. It is a slow and steady decline with the disease usually lasting from 15-20 years. Although progression speeds vary among people, it will eventually lead to full time dependency and needing care.

  Stage 2: HD gene present, biomarker changes, and clinical signs. This stage begins when a patient shows clinical signs of Huntingtons disease. […] Stage 3: HD gene present, biomarker changes, clinical signs, and difficulties with daily function. The last stage begins when a patient experiences functional decline, such as difficulty carrying out day-to-day tasks. Additionally, stage 3 is broken up into mild, moderate, and severe functional decline. […] The amount of time spent in each disease stage will differ from person-to-person. How quickly an individual progresses through each stage is variable, but strongly depends on age and CAG repeat length. […] The HD-ISS will help standardize clinical research by categorizing patients in a more predictable way. This will allow clinicians conducting clinical trials to more quickly select research participants for studies who are likely to have a similar disease course or respond similarly to a treatment. Standardizing the categorization of different stages of Huntingtons disease, particularly between birth and the onset of clinical symptoms, is necessary to help the field move toward testing drugs earlier, before clinical symptoms are apparent.

• #140 Huntington’s disease – Wikipedia

  https://en.wikipedia.org/wiki/Huntington%27s_disease

  The most characteristic initial physical symptoms are jerky, random and uncontrollable movements called chorea. Many people are not aware of their involuntary movements, or impeded by them. Chorea may be initially exhibited as general restlessness, small unintentionally initiated or uncompleted motions, lack of coordination, or slowed saccadic eye movements. These minor motor abnormalities usually precede more obvious signs of motor dysfunction by at least three years. The clear appearance of symptoms such as rigidity, writhing motions, or abnormal posturing appear as the disorder progresses. These are signs that the system in the brain that is responsible for movement has been affected. Psychomotor functions become increasingly impaired, such that any action that requires muscle control is affected. When muscle control is affected such as rigidity or muscle contracture this is known as dystonia. Dystonia is a neurological hyperkinetic movement disorder that results in twisting or repetitive movements, that may resemble a tremor. Common consequences are physical instability, abnormal facial expression, and difficulties chewing, swallowing and speaking.

  Huntington disease is a hereditary disease that causes random, flowing movements that are involuntary and cannot be suppressed (called chorea). The disorder progresses to more pronounced involuntary movements (sometimes writhing movements, called athetosis), mental deterioration, and death. […] Symptoms of Huntington disease usually develop subtly, typically beginning between the ages of 35 and 40 but sometimes before adulthood. During the early stages of Huntington disease, the face, trunk, and limbs may move involuntarily and rapidly. At first, people can blend these abnormal involuntary movements into purposeful ones so that the abnormal movements are barely noticeable. However, with time, the movements become more obvious. […] Muscles may contract briefly and rapidly, causing the arms or another body part to suddenly jerk, sometimes several times in a row. People may walk in a lilting or exaggeratedly jaunty way, like a puppet. They may grimace, flick the limbs, and blink more often. Movements become uncoordinated and slow.

  Huntington disease is a hereditary disease that causes random, flowing movements that are involuntary and cannot be suppressed (called chorea). The disorder progresses to more pronounced involuntary movements (sometimes writhing movements, called athetosis), mental deterioration, and death. […] Symptoms of Huntington disease usually develop subtly, typically beginning between the ages of 35 and 40 but sometimes before adulthood. During the early stages of Huntington disease, the face, trunk, and limbs may move involuntarily and rapidly. At first, people can blend these abnormal involuntary movements into purposeful ones so that the abnormal movements are barely noticeable. However, with time, the movements become more obvious.

  Myoclonus is commonly observed in patients with juvenile-onset HD and is rarely reported as a predominant and disabling motor feature in patients with adult-onset HD. […] As the disease progresses, chorea often spontaneously subsides in HD patients. However, parkinsonism can develop and progress to akinesia, severe rigidity, and mutism in the final stages. […] In HD, the progressive deterioration of voluntary motor control is prevalent in gait, balance, coordination, oculomotor function, swallowing, and speech. This deterioration is correlated with an acceleration of functional decline. […] After clinical manifestation, HD patients exhibit steady neurological deterioration. Many studies have attempted to measure the progression of HD. The annual progression rates derived from the results of these studies are summarized in Table 2. Notably, although most neurological symptoms steadily deteriorate after onset, chorea progresses quickly in the early stages and reaches a plateau before worsening as the disease progresses.

  Chorea is the prototypical and most common motor manifestation of HD, occurring in 90% of affected patients. Chorea is more common in adult patients than in juvenile patients, and it typically initiates in the early stages, plateaus, and regresses during the late stages of the disease. […] Symptoms of chorea in HD patients vary in severity, affecting other motor and nonmotor symptoms (NMSs), daily activities, hospitalization, and quality of life. As chorea progresses, patients experience recurrent fall injuries due to postural instability and gait disturbance. […] The prevalence of dystonia is reported to be 91%-95% in adult patients, and the most affected body region is the upper limbs, with internal rotation of the shoulder and sustained fist clenching. Dystonia worsens as the disease progresses, and its severity is correlated with disease duration and the use of antidopaminergic agents.

  Huntington’s disease (HD) is a rare, monogenic neurodegenerative disease characterised by a triad of cognitive, behavioural and motor symptoms leading to functional decline and progressive loss of independence. It leads to functional decline and loss of independence, and results in death on average 15 years after the onset of motor symptoms. Cognitive disturbances in HD can occur years before diagnosis and onset of motor symptoms, and deteriorate steadily as the disease progresses. […] Behavioural manifestations in HD are particularly diverse and can also occur many years before a clinical diagnosis of HD is made. Motor symptoms in HD are initially subtle and progress in a non-linear trajectory over the course of the disease. […] HD is a continuum which can be described in three stages. Clinical diagnosis of HD is typically defined by the onset of unequivocal motor symptoms and occurs when people are in the prime of life, typically between the ages of 30 and 50 years. […] Individuals experience subtle changes in cognition, mood and behaviour that appear years before diagnosis or onset of unequivocal motor signs. Brain changes, including striatal atrophy, are apparent. […] Individuals with HD have unequivocal motor symptoms and are clinically diagnosed with HD.

  Some people with HD do not develop chorea; instead, they may become rigid (stiff) and move very little or not at all. This condition is called akinesia. Other people may start out with chorea but become rigid as the disease progresses. […] Physical changes may include slurred speech and problems with swallowing, eating, speaking, and especially walking. People with HD may lose weight because of problems with feeding, swallowing, choking, and chest infections. Other symptoms may include insomnia (having trouble sleeping), loss of energy, fatigue, and seizures. Eventually the person will need to stay in bed or in a wheelchair. […] Changes in thinking (cognitive changes) may include problems with attention or judgment and having difficulty solving problems or making decisions. Other changes may include trouble with driving, prioritizing (deciding which things are more important to do and which are less important), and organizing, learning new things, remembering a fact, putting thoughts into words, or answering a question. These cognitive changes get worse as the disease progresses, until people with HD are not able to work, drive, or care for themselves.

[…] About 10% have onset of motor symptoms after age 60 and 10% have Juvenile onset HD, where symptoms manifest before age 20. […] The movement disorder of HD includes emergence of involuntary movements (chorea) and the impairment of voluntary movements, which result in reduced manual dexterity, slurred speech, swallowing difficulties, problems with balance, and falls. Chorea typically progresses through the middle stages of HD, but often declines as rigidity increases in the later stages.

  Signs and symptoms of Huntington’s disease most commonly become noticeable between the ages of 30 and 50 years, but they can begin at any age and present as a triad of motor, cognitive, and psychiatric symptoms. When developed in an early stage, it is known as juvenile Huntington’s disease. In 50% of cases, the psychiatric symptoms appear first. These can precede the motor symptoms by many years. Disease progression is often described in early stages, middle stages and late stages with an earlier prodromal phase. In the early stages, subtle personality changes, problems in cognition and physical skills, irritability and mood swings occur, all of which may go unnoticed. Almost everyone with HD eventually exhibits similar physical symptoms, but the onset, progression, and extent of cognitive and behavioral symptoms vary significantly between individuals.

  Cognitive deficits in HD generally manifest as a decline in executive function, with patients frequently having increasing difficulty with attention, concentration, multi-tasking, and decision making. Depression and loss of memory and insight are also commonly observed. The psychiatric symptoms of HD are broad, and prior to the onset of motor symptoms, patients may be mistakenly diagnosed with a primary psychiatric disorder. Anxiety, obsessive-compulsive disorder, mania, and psychotic symptoms, including hallucinations and delusions, may also be observed, but depression, irritability, and increased impulsivity are most commonly reported. […] While unrelated to the three domains mentioned above, weight loss and cachexia are also frequently observed. Human HD patients and HD mouse models have both been demonstrated to exhibit hypermetabolic states and negative energy balances.

  Huntington disease (HD) is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Mean age at onset of symptoms is 30-50 years. In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at school (Juvenile Huntington’s disease; JHD). The classic sign is chorea that gradually spreads to all muscles. All psychomotor processes become severely retarded. Patients experience psychiatric symptoms and cognitive decline. The progression of the disease leads to a complete dependency in daily life, which results in patients requiring full-time care, and finally death. The most common cause of death is pneumonia, followed by suicide. […] The nuclear symptoms and signs of Huntington’s disease (HD) consist of motor, cognitive and psychiatric disturbances. Other less well-known, but prevalent and often debilitating features of HD include unintended weight loss, sleep- and circadian rhythm disturbances and autonomic nervous system dysfunction. The mean age at onset is between 30 and 50 years, with a range of 2 to 85 years. The mean duration of the disease is 17-20 years. The progression of the disease leads to more dependency in daily life and finally death. The most common cause of death is pneumonia, followed by suicide.

In stage 1, there are measurable indicators of HD pathophysiology, and in stage 2, there is a detectable clinical phenotype. In stage 3, functional impairment is present. Each stage is anchored on well-defined landmark assessments with cut-off scores for clinical and/or neuroimaging markers. […] The field of HD therapeutics is experiencing a new phase with experimental therapies targeting the pathogenic mHTT protein to slow disease progression. The first results of human clinical trials have been disappointingly negative but carry forward knowledge to present and future clinical trials of other HTT-lowering therapies.
